LEWIS s. HAYES, or CORTLAND, NEW YoRK.

Moron-mow.

Cortland in the county. of Cortland, in the .State of New York, have invented new anduseful Improvements in Motor-Plows, of which the following, taken in 1 connection with the accompanying drawmgs, 1s a full,

' clear, and exact'description This invention relates to certain improvements in motor-dr1ven plows having a wheel truck adapted to carry any of the well known forms of steam or gas engines or equivalent motors and suitable mechanism 'for transmitting motion from the motor to one of, the traction Wheels for propelling the machine; in either direction.

'll1e-inain ob ec t is to provide the motordriven truck with. aplurality of plowsfao ing each. other and movable independently into and out of their operative.positions so. that the machine maybe driven in either. direction for. plowing successive furrows without turning the'inachine around.

' me mhers. will always travel 'or unturnedground.

I in opposite directions so as to permit short and quick turns when desired,

Other objectsare to permit the use of a harrow tin connection with the active plow or plows .so .-as tofinish the $011 for plant ing simultaneously w1th the plow and also to support the plows and harrows in such manner as'to relieve as far as possible the excessive strains upon their hinged connectionsuwith the truck.

i 0 her objects and uses relating to specific parts of 'theymachinewill be, brought out inv the following description. v

same low takenon line3,3 Fi 1 showing more particularly the .manner of raising and loweringeach set of plows and the corresponding harrow. Fig. 4 is a detail sectional view ofv a portion of the harrow frame showing the manner of locking it in its inoperative position.

The plow truck, constituting one of the importantfeatures of my invention, comprises a main supporting frame or platform -1-, a traction wheel 2, and steering wheels 3, the traction. wheel being mounted upon a'transverse shaft. +l centrally upon one side of the frame 1 and substantially midway between the ends thereof while the steering wheels 3- are mounted upon axle stubs 5 on the ends of the opposite side of said frame.

The shaft 1 for the traction wheel may be driven by any of the well known forms of inter/nal combustion or steam engines and power transmitting mechanism not shown) 1 and for this purpose I have provided the shaft with a gear 6 for connection to such motor although it is evident that anyother driving'member may beemployed according to the disposi- .tion ofthe notorontlie truck.

The traction wheel -2- may be of any suitable size or construction to afford the necessary gripping'power sufiicient to propel the entire machine along the surface of the ground when one or the other set of plows is in active position. I

It will be observed that the entire frame. is underslung below the shaft or axle 4 so as to bring the plow supports and plows in close compact relation to the frame,

thereby reducing the strains upon said supports and their connection with the main frame. r

Suitable plate-supporting frames '7. are pivoted at 8 to brackets '9 'on the same side of the frame 1 at opposite sides of and equi-distant from the axis of the traction wheel 2 so as to swing vertically transversely of the main frame through an arc of substantially 90 to and from a horizontal position, each frame being two, pendant brackets 10 for receiving and supporting corresponding number ,of-

provided with one or more, in this instance plows 11 having specially formed land sides which are rigidly secured directly to the lower ends of theirrespective brackets. These brackets are rigidly secured to Y'ih'nllnl lengthwise bars forming parts of the swinging frames and spaced some distance apartv so as to support'tlie plows side by side a distance corresponding to the desired width between adjacent furrows, the outer brackets 7 ends serve as limiting stops or rests 13- for li iiiiting the downward movement of the swinging frames and plows mounted thereon and at the same time permitting free upward movement of the swinging frames and plows when not in use.

The plow supporting frames with the plows thereon may be moved to and from their active positions by anysuitable means here shown as consisting of a hand lever 1l having one end rigidly secured'to the outer portions of the main supporting frames and adjacent brackets -10- and their opposite ends extended upwardly some distance above their corresponding swinging-franies and provided with suitable handles --l5 by which they may be manipulated, each lever being provided with a movable detent --1t$. operable by means of a link l7 and hand piece 18 for engagement with an upstanding flange or bar "11)- rising from the main supporting frame, said bar being rigidly held in 0perative position by braces Suitable liai-ro\\'-supportingframes -21- are also pivotally iiiouiited upon the same iivots S as the ilow-su )ortin frames l s so as to rest thereon when adjusted for use but are capable of independent vertical swinging movement through an arc of substantially ill) to and from a horizontal position and are provided with teeth-supporting bars -2'. carnving a series of liarrowte'eth l-', the bars and teeth being-arranged diagonally lo the line of travel with their outer entls l'oreiiiost so as to level all the "furrows as tliev are made by the plows thus preparing the soil For meadow planting, in a single operation ol the nneliii-ie.over the surl'ace ol' the ground, it being understood that, each liarrow frame is arranged so that its teeth trail on the ground just at, the rear of the plows astlie machine is propelled l'orwart'lly.

y it \villlie observed upon reference to Figs. 1 and 2 that the inner sides of the plow-supporting frames and liarrow;supporling frames are 'liinged between ears or lugs forming parts of the brackets t)-- which serve to relieve in'a measure the pivots from excessive strains, but in addition to these features, the ends of the auxiliary frame 12 are also provided with forwardly pro ecting lugs -22 for engaging the rear face of the front end bar of the plow-supporting frame 7- which may be adjusted for use, said lugs -'2'2 being located some distance outside of the hinged connection between the swinging frame and main supporting frame so as to draw directly upon the active swinging frame and thereby further relieve the hinges from excessive strains during the plowing operation.

I Any suitable mechanism may be provided for operating the steering wheels -.3- simultaneously in opposite directions; so as to effect short or quick turns and for this pur pose, the axle stubs -5 are pivoted at to the adjacent ends'of the main supporting frame '1 and are provided" with crank arms 24projecting inwardly toward each other, said crank arms being connected by. separate links 25 to additional crank arms -2G on the opposite ends of alongitudinally extending rock shaft 27, This rock shaft preferably extends from end to end of the main supporting'frame and is journaled in suitablebearings therein, the central portion of said rock shaft being, provided with a toothed segment 28 which is engaged by an uprightworm 29 on the lower end of a vertical steering post '30 having a suitable hand wheel by which the worm may be turned in either direction for "operating the toothed segment and thereby transmitting corresponding turning. motion. to the steering wheels through the medium of the crank arins 2(3 and -2-t and link 25-.

When either plow is used independently versely ol' the frame about. the saute axesand that these plow frames and plows are located Ill approxin-iately the line-0t travel of the tl'aclioli wheel and at the same side ol the main supporting l'ranie and equidistant from said traction wheel; that the 4 plows of both sets face each other and therefore face the'trtu-tion wheel which is located approximately midway between the ends of the frame while the steering wheels I are located at opposite ends of the machine v and at the opposite side of the main frame simultaneously iii-opposite directions; that either plow and .its corresponding harrow frame may be thrown into and out of position imflependently'of the other plow and its harrowframe and that either harrow frame may be used simultaneously with the corresponding plow or held in its inoperative position as may be desired, thereby permitting the machine=to be moved back and forth across the field by simply adjusting one or other of the-"plows to its operative position and raising the other plow to its inoperative position, the active plow being always at the r rear of the traction wheel whereby the traction wheel is always traveling on solid ground.

What I claim is: 1. In a motor plow, a truck having only three ground l. ea.rings, all disposed in the same plane, two of said bearings being'located at one side in the same line of draft and turnable laterally for steering, the other bearingbeing a traction whee-l located at the opposite side of the machine substantially midway between the steering bearings, plow supporting frames hinged to the truck to swing transversely of the line of draft and extending some distance beyond the outer side of the line of travel of the traction wheel, and plows mounted on said frames to move therewith. Y 1

2. In a motor plow, a truck-frame having three ground-wheels constituting its only support and having their ground bearings in the same horizontal plane, two of the wheels being located at the ends of one side of the frame, the other wheel being located near the center of the opposite side of said frame and constituting the. only traction wheel, and separate plow supporting frames hinged to the frame to swing vertically at right angles to the line of draft.

3. In a motor plow, a truck-frame, and three supporting wheels only therefor, ,said wheels having their lower sides disposed in the same plane parallel with that of the EI'HIYIQf-UVO' of said wheels being upon the opposite ends of one side of the frame, the other wheel being mounted on the center of the opposite side of the frame and constituting the only traction means, means for turning the first-named two wheels laterally for steering purposes, and plow-supporting frames hinged to the frame to swing vcrtically and transversely of the line of draft and extending laterally some distant-e to the outside of the line of travel of the traction wheel when adjusted for use.

4. In a motor plow, a three-wheel truck in which twb of the wheels are mounted upon opposite ends of one side of the main supporting frame to turn laterally for steering purposes, the other Wheel being mounted upon the central portion of the opposite side of said frame and constituting the only traction means, the lower faces of said wheels being disposed in the same horizontal planeto travel upon the surface of the unplowed ground, and plow-supporting frames mounted for vertical movement upon opposite ends of the same side of the frame as the traction wheel and extending outwardly beyond the line of travel of said tractionwheelv y In a reverse drive motor plow, a 'trucle frame having three supportingwheels only, two of the wheels being mounted upon opposite ends of one side of the trucleframe to turn laterallyfor steering, the other wheel being mounted upon the center of the opposite sidelof the machine and constituting the only traction wheel, and plow-supporting 1 frames hinged to oppositeends of the truckframe at the front and at the rear of the traction wheel to swing vertically and transversely of the line of draft of the machine, andseparate devices for holding the plowsupporting, frames in their elevated posi\ tions.

6. In a reverse travel'inotor plow, a truck frame having two steering wheels located at opposite ends of one side of the frame and separate plow-supporting frames located at opposite ends of the opposite sides of said frame and hinged to the frame to swing vertically transversely of the line of draft, and a single traction wheel mounted on'th'e same side as and between the plow-supporting frames.

7. In a reverse tnavel motor plow, a truck frame having two steering wheels located at opposite ends of one side of the frame and separate plow-supporting frames located at opposite ends of the opposite side of said frame and hinged tothe frame to swing vertically transversely of the line of draft, and a single traction wheel mounted. on the same side as and between the plow-supporting frames and having its lower traction face disposed in substantially the same horizontal plane as that of the steering wheels.

In witness whereof I have hereunto set my hand this 1st day of May 1.913.
